Is ETFA p.Asp82Val (c.245A>T) pathogenic?

ETFA p.Asp82Val (c.245A>T) is classified Uncertain significance in ETFA (ClinVar, Single submitter, 1 submitter; last evaluated 2022-03-10). AlphaMissense: likely benign (0.2458); Very rare (popmax 0.00167%, amr); Associated with multiple acyl-CoA dehydrogenase deficiency.

What condition is associated with ETFA p.Asp82Val (c.245A>T)?

ETFA p.Asp82Val (c.245A>T) is associated with multiple acyl-CoA dehydrogenase deficiency (ClinVar).

How common is ETFA p.Asp82Val (c.245A>T) in the general population?

ETFA p.Asp82Val (c.245A>T) is very rare (popmax 0.00167%, amr) (gnomAD).

How is Multiple acyl-CoA dehydrogenase deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about ETFA p.Asp82Val (c.245A>T)?

AlphaMissense predicts likely benign (score 0.2458) — an in-silico prediction, not a clinical call.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
